|Note: these eyepieces and barlow lens are not
filters and for Solar observing must be used in conjunction with a Coronado Ha Solar Telescope.
The CEMAX (Contrast Enhanced) series eyepieces are specially designed
and coated for optimising Ha viewing. In the construction of Solar
filters and associated instrumentation, Coronado takes enormous care
to optimise contrast by minimising the number of components and designing
them so that they do not result in creating residual reflections and
spurious light near the image.
Until now, the only component not included in this overall approach was
the eyepiece. Now the new CEMAX SERIES fills this need. Specifically
designed for use at Ha and multi coated on every surface (including
cemented surfaces), the CEMAX eyepieces are the ultimate in contrast
enhancement for the Solar observer. 20mm eye relief. Apparent FOV52 degrees.
The CEMAX SERIES are currently available in focal lengths of 25, 18 and 12 mm.
A fully complimentary and similarly optimsed, X2 Barlow lens is also available
for increasing the magnification options.

The CEMACAX 4-piece eyepiece and barlow lens includes all three CEMAX eyepieces
(25mm, 18mm, 12mm), the CEMAX barlow lens and a case.
